Static Semantics

The declaration of the generic library package Containers.Indefinite_Hashed_Sets has the same contents and semantics as Containers.Hashed_Sets except:

The generic formal Element_Type is indefinite.

The actual Element parameter of access subprogram Process of Update_Element_Preserving_Key may be constrained even if Element_Type is unconstrained.

The operations Include, Insert, Replace, Replace_Element, and To_Set that have a formal parameter of type Element_Type perform indefinite insertion (see A.18).
